SADIRON Filed July 2, 1928 INVENTOR. HFIRRY L. EIBENBRDT Patented Apr. 8, 1930 UNITED STATES PATENT OFFICE I HARRY L. EIGE'N'BROT, OF SAN FRANCISCO, CALIFORNIA simmer:

Application filed July 2, 1928. Serial No. 290,010.

This invention relates to improvements in electric iron attachments, and has particular reference to an attachment for use with the ordinary clothes-pressing sad iron.

The principal object of this invention is to provide a switch positioned upon the sad iron, which switch may be operated either manually or thermostatically.

Another object is to provide a device of this character which is simple in construction and one which may be attached to the ordinary 'iron without altering the construction of the same.

I have provided switch secured to the handle of the sad iron, which switch is operated by the hand of the .operator.

In the accompanying drawings forming a part of the specification and wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates the base or body of the iron proper, which base may be of any convenient form capable of use in smoothing clothes. This 6 base carries an upstanding U-shaped metal support 6, between the ends'of which is positioned a handle 7. The usual heating element is designated at 8 and the socket is shown at 9. This socket is of the usual construction, and serves to connect the iron to the source of electrical energy.

The construction thus far is found in all irons and forms no part of my invention.

In accomplishing my object I employ a.

thermostatic rod 11, one end of which engages the heating element 8 while the op-' A further object is to provide a device posite end is in close proximity to the handle 7. -The upper end is provided with an adjustable extension 12, which extension underlies the short arm 13 of a pivoted switch lever 14. This lever is pivoted as at 16 and due to the difference inlength between the arm. 13 and the lever 14, it is apparent that a very short movement of the thermostatic rod 11 will cause a considerable movement of the lever 14.

- The end of the lever 14 is adapted to engage a contact 17 carried upon the end of a a tapered lever 18. This operating lever is mounted upon a traveling pin 19 carried in a slot 21 formed in the handle 7.

'A thumb piece 22 provides a convenient means for moving the sliding pin 19.

A contact 23 serves to conduct electric current from the wire 24, which wire is in turn connected to the socket 9, to the operating lever 18. The switch 14 is connected by a wire 26 to the. heating element 8, which heating element-is in turn connected to the socket 9 thus completing the electrical circuit.

The manner in which my device operates is as follows contact 17, operating lever 18, contact 23 to wire 24 and back to the opposite side of the socket 9.

When the heat of the iron has reached a pre-determined amount, the rod 11 will expand and will cause the switch 14 to move out of engagement with the end of the lever 18, as shown in dotted lines of Figure II. This will break the circuit, and consequently the iron will cease'heating.

\ Upon a cooling of the iron, the rod 11 will contract and close the switch 14 and heating will occur.

When the operator is using the iron, the grasping of the handle will pushupwardly upon the lever 18 and hold the same in contact with the switch 14. Therefore, the iron will remain on heat during the ironing operation, lfilless the operator wishes to disconnect the electric circu't in which event, the

thumb piece 22 is pushed forwardly which will move thetapermg lever 18 to the dotted 5 line position of Figure II.

It will thus be seen that I have produced an ironhaving a control mechanism therein which will perform all of the objects herein set forth.

It is to be understood that the form of my invention herewith shown-and described is to be taken as a preferred example of the same, and that various changes relative to the shape, size, material and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described my invention, I claim In a device of the type described a heat ing element positioned therein, and a handle positioned therein, a rod contacting said heating element and having its opposite extremity in close proximity to said handle, a switch lever pivotall mounted in said handle and adapted to actuated by said rod, an operating lever ivotally mounted in said handle and adapted to contact said switch lever and means for moving said lever into'and out of so engagement with said switch lever by shifting the 'pivotal point of said tapering lever.

In testimon whereof I aflix my signature.
